Complex hiatus hernias. Diagnostic and therapeutic management recommendations.

Abstract

Hiatus hernia (HH) is a relatively prevalent condition in our setting, yet there is little clinical evidence or guidelines establishing precise recommendations for its diagnostic and therapeutic management. In order to establish clinical recommendations for the diagnostic and therapeutic management of patients with complex hiatal hernia, defined as a primary type III or IV mixed hernia, a large one with >30% of the gastric contents in the thoracic cavity, or a recurrence. This document was prepared based on current scientific evidence and the experience of a group of 28 expert surgeons, using GRADE methodology in order to establish recommendations on 13 controversial aspects related to this pathology. Although the quality of evidence and the degree of recommendation are high in some areas, high-quality prospective clinical studies are needed to clarify certain unresolved points of controversy.
